Getting your Mac OS X App ready for the App Store is simple. Until you start thinking about verifying the store receipt, checking the certificate chain used to sign your application and checking the integrity of the application bundle.

Implementing all of the WWDR recommendations for the App Store could take up to a month (that's the voice of experience speaking), even for experienced developers!

Tighten Pro changes all that. With a built-in code generator that reads directly from your codesign-ed app bundle, you can add a complete, robust App Store implementation to your own application in under 30 minutes.

And since the code generator creates customized security code, your app will be more secure than if you simply reused sample code from the internet.

Tighten Pro was used to add App Store code to both Reducticon and FaceBoof! in under an hour.

Compare that to the author's first attempt at store receipt validation by modifying sample code from the internet, which took over a day and only addressed a subset of the recommended validation checks.

This Pro version of Tighten includes a code generator that creates robust implementations of App Store receipt validation code, complete with customized security checks based on your Mac Developer identity, your app Bundle ID and the WWDR certificate chain.

Tighten Pro will generate code unique to your app and is able to save up to 30 days of work per-implementation. Use it over and over again for all your little Apps. Reduce piracy, increase developer productivity, have plenty of time to watch this week's episode of Caprica or V.NOTE: To buy Tighten Pro via the App Store an Apple account is required.
